Live
Start a live voice session with Nebula and your teammates from Home, a thread, or a channel — talk it through while agents work in the background.
You can talk to Nebula out loud. Start a call from anywhere in your workspace, bring teammates in, and the work you discuss gets picked up and run while the conversation keeps going.

On it — dispatching to @sentry-monitor-agent.
A call is a thread like any other — it lands in your feed, keeps its history, and leaves behind a transcript and a summary when it ends.
Starting a call
Every entry point opens the same Start call dialog.
The composer on Home has a call button next to the message input. Starting from here creates a fresh thread for the call — you don't have to pick one first.
Open any thread and use the call button in the composer to talk through what's already in it. The call attaches to that thread, so its history is the context.
Start a call from a channel to pull in the people already working there. Workspace-visible calls show up for the channel's members.
Live in the top header lists everything live and everything past. New session starts one.
You'll see two words for this. Live is the destination — the header entry, and this section of the docs. A session is one instance of it: the page lists Sessions, the button reads New session, and a channel's sidebar keeps a Sessions section. Inside the room itself the controls still say call, which is the same thing again.

Name it — optional. "What's this call about?" becomes the call's title in your feed and history. Skip it and the recap names it later.
Pick visibility — Workspace lets anyone in the workspace join; Private is invite-only. Workspace is the default.
Invite people — teammates who are online float to the top with a live dot, and Add all grabs everyone who's around right now. The button reads Start with 2 once you've picked people.
Calls run right in Nebula — in your browser or the desktop app. You drop into the room the moment you start, and the header reads Nebula is joining until your agent connects, so you always know where things stand. On desktop, the Capsule keeps call controls on screen even with the main window closed.
Who's on the call
Every call runs one agent — your orchestrator. It's the voice you talk to, and it decides what to hand off.
The clever part is that it wears each person's identity. When Priya talks to it, it answers as her default agent; when you talk to it, it answers as yours. Each person's agent name works as a wake word — say it out loud in a group call and the agent speaks up without anyone reaching for a button, and you can add your own wake words too. On a call by yourself, there's no one to pair with — your agent simply stands on its own.
Specialists — @sentry-monitor-agent, @github-agent, and the rest — don't join the call. They pick up dispatched work in threads and report back, which is why the work board fills up while you're still talking.
How talkative your agent is during the call is up to you — see active and background agents.
Where calls live
One list of every call — live ones pinned to the top, the rest ordered by recent activity. Filter to just yours or everyone's.
Live calls float to the top of your feed. Opening one takes you into the call, not a chat thread.
When a call ends it doesn't disappear — the ended view keeps the recap and the archive, and Start again opens a fresh call seeded from the same thread.
Calls draw down Nebula Credits while they're live, billed once per call rather than per person on it. Tool Credits don't cover calls, so a call stops when Nebula Credits run out even if Tool Credits are full. See nebula.gg for current plan details.
Showing your agent something
A call isn't only talking. You can put something in front of your agent and ask about it directly.
Sharing your screen
Show what's on your computer and ask what it says — a dashboard, an error, a stack trace you'd rather not read aloud.
Live camera
Turn on your webcam and hold something up. Good for labels, hardware, and whiteboards.
